Hello,

I built an automatic test bench with the Logo! This has all gone smoothly, but there is one thing I cannot immediately find a solution for...

In the current version, the operator must manually enter the test parameters.This creates a risk of mistakes and therefore I'm looking for an alternative way of inputting the parameters.

My first idea was, to put on a CVS-list of all products and their corresponding parameters on the SD card.That way, the operator only has to select the product name. This turns out to be not so straightforward to realize in Logo!

An alternative that might even be better than the original idea is to work with a 1D or 2D barcode scanner. The amount of input data is limited and can fit in a QR code. But it also turns out that it is not so obvious to link a standard Barcode scanner with the Logo!

I've been getting stuck on this for a while now.

Can anyone help me move forward with this? Is there any way that either of these 2 ideas can be realised anyway?

Or does anyone have a totally different idea? 

Thanks!

Without further details on the dates and quantities as well as formats ...

Who should make you a suggestion ?

I am not expecting a fully developed concept, but I was hoping someone of the experienced people here could point me in the right direction. 

If this forum is not intended for this kind of specific application related questions, I wish to apologize and a moderator may remove this thread.

Best regards,

Johan

If it is not known what amount of data is involved, what format the data is in, how should a suggestion be made?

And if I am not allowed to ask questions and I am immediately accused of incompetence, then this topic is settled for me.

Good luck ....

I cannot consider someone who has published over 25,000 posts on this forum to be incompetent! 

When I speak of 'experienced people on this forum', I want to emphasise that I myself am a complete newbie when it comes to Logo! 

Sorry if this can be misinterpreted.

The logo is not able to work with recipes.

Although the Logo can write to a CVS file with the log module, it cannot read it itself and process it programmatically.Therefore there is no possibility with a barcode scanner.

If the data sets are very few, they could be stored in Muxern. However, this only works if there is still enough memory available in the program.

Another possibility would be to outsource the operation and the values and write them in the logo. I could imagine that something can be done with Node-Red or other comparable systems. A Raspberry Pi should be enough for this.

I misinterpreted your first response, which made me think my question was inappropriate on this forum for being too application-oriented. Hence my reply about deleting the post. Sorry for that.
